L-Tyrosine can be used to improve alertness, concentration and focus

Tyrosine is a conditionally essential amino acid which means that it can become essential in certain cases. Under normal conditions the body can synthesize sufficient quantities from the amino acid phenylalanine but in certain cases it can become depleted.

Exercise performance: Various forms of stress can have a detrimental effect on performance and health. The decrements in performance usually result from stress which is due to the depletion of catecholamines and the neurotransmitters ephinephrine and dopamine. Supplementation with tyrosine may lead to better mental focus, alertness and mental arousal by preventing the depletion of neurotransmitters; this helps to reduce the level of stress hormones in the body.

Tyrosine and memory: Tyrosine has also been postulated to improve memory under stressful situations. Tyrosine is suggested to help to improve cognitive function and improve memory by reducing the depletion of neurotransmitters which are associated with decrements in cognitive function.

Fat loss: Tyrosine may also have an important role to play in fat loss. It has been shown that tyrosine supplementation in conjunction with other active ingredients such as capsaicin, catechins and caffeine can suppress appetite and aid fat loss by stimulating thermogenesis.
